The name Trew is of Cornish origin and is derived from the Cornish word 'trev', meaning 'sacred grove' or 'holy place'. It is a unisex name, often used more commonly for males in Cornwall but can also be found among females in other parts of England. The name was popularized by the Cornish saint Trewithian (also known as Trew), who lived in the 7th century and founded several churches in Cornwall. The name is unique and uncommon outside of Cornwall, making it a distinctive choice for parents looking for a distinct and meaningful name for their child. It has no traditional nicknames or variations, allowing the bearer to have a truly unique name.
"Over fifteen years, from 1999 to 2014, the name Trew was given to a total of sixteen newborns. However, there's a notable gap in usage between 1999 and 2004, with no recorded births during those five years."
